901250-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 901250-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,1,2,5 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 901250-69:
(8*9)+(7*0)+(6*1)+(5*2)+(4*5)+(3*0)+(2*6)+(1*9)=129
129 % 10 = 9
So 901250-69-9 is a valid CAS Registry Number.

experimental part, p. 215 - 218 (2010/03/01)
Monosubstituted oxadiazoles were synthesized by the reaction of hydrazides with triethyl orthoformate. Their reactions with benzoyl chloride gave benzoylcarbohydrazides, which under the action of thionyl chloride were cyclized to the respective 2,5-disubs
